This work presents a high-throughput selected reaction monitoring (SRM) LC-MS method for the determination of methylphenidate (MPH), a central nervous stimulant, and its de-esterified metabolite, ritalinic acid (RA) in rat plasma samples. A separation of these two compounds was achieved
Methylphenidate is a frequently prescribed stimulant for the treatment of attention deficit hyperactivity disorder (ADHD). An important assumption in the animal models that have been employed to study methylphenidate's effects on the brain and behavior is that bioavailability of methylphenidate
Methylphenidate (MPH) is a stimulant medication widely used for treating attention-deficit hyperactivity disorder (ADHD) in children and adolescents. Therapeutic monitoring for this drug is essentially lacking and alternative biological matrices, such as oral fluid and sweat, should be investigated for

Stereoselective urinary pharmacokinetics of dl-threo-methylphenidate (MPH) and its major metabolite, dl-ritalinic acid (RA), were examined in a cohort of healthy subjects. On two occasions, separated by one week, each subject received MPH.HCl either intravenously (10 mg) or orally (40 mg).

Methylphenidate (MP, Ritalin) is a psychotropic drug widely prescribed to children for treating the symptoms of attention deficit disorder with and without hyperactivity. Because little information exists about the effects of chronic MP administration on cognitive function in children, measures
